Add a Photo Mechanic style edit only feature to Lightroom for faster workflow in the Library Module

Add an edit only feature to the Lightroom Library Module that works like photo mechanic, so that Lightroom does not have to render the full previews that slow it down when reviewing images for focus, composition, making picks and rejects, etc., not for developing. At which point, LR would use the previews it makes with the applied color data

In the mean time, consider manually initiating preview building whenever you plan to do some reviewing in the library module - if up-to-date previews already exist, Lr lib preview display is pretty-darn fast.

Thanks, Rob. I do build 1:1 previews at the time of import or manually initiate build previews when the previews have been discarded. Shooting with 36.3MP files, it's a killer when reviewing 1000 images from a shoot. Fast is relative...

I rebuild previews frequently, and so rarely have any loading time - I can step through dozens of previews (regardless of original resolution) in just a few seconds. I'm not bragging, just saying: if previews are current, then Lr can sequence through them relatively fast, so it's a really good idea to initiate building whenever you plan on traversing a few, not just during import, or once discarded. Lr is smart enough not to recreate those that are already up-to-date, so there is really no reason not to. I have a button on a widget that I click multiple times per day (works regardless of module I'm in), but the lib menu is fairly convenient too once you get used to it - consider wiring a single preferred keystroke via AutoHotkey or the like..

Don't get me wrong: I'm all for (Adobe) improving library module performance, but until then, keeping previews current is a must if you don't like delays whilst culling - Lightroom (versions 1-5) won't do it for you (fingers crossed for Lr6).

PS - I get that during import you have to wait, period, which is a bother.. and there are a few different flavors of remedy which have already been suggested in this forum, at least one was submitted by me ;-).
